If you are a more-than-average type of computer user, then you would have felt the need of adjusting the computer screen brightness. The need comes because of the vast difference in the ambient lighting conditions of day and night.
Most of the Computer / Laptop / LCD screen brightness are adjusted for the day conditions. When you start your computer in night, it just starts with a blinding effect.
